Sent my King off to tarty, so I decided to put on a freewheel and my old unsealed Onza hub, I killed that in a day, so Ive now got a sealed onza hub, but cannot get the cog off, I have only got 4 teeth left on the hub from hitting it with a hammer & an ally strip etc. Ive tryed sawing it down to the thread but that didnt work, any ideas? I need to ride. Mat
